CARTRIDGE CONTAINING CQMFRESSED OR LIQUEFIED GAS FOR INFLATING LIFE- ]?RESERVING BELTS, PNEUMATIC TIRES, AND OTHER PURPOSES.

Application filed October 14, 1916.

To all whom it may concern:

Be it known that l, VVILLJAM GOULD BRO- KAW, a citizen of the United States, whose post-otlice address is 4E1 Boulevard l-laussmann, Paris, France, have invented new and useful Improvements in Cartridges Containing Compressed or Liquefied Gas for inflating Life-Preserving Belts, Pneumatic Tires, and other Purposes, of which the following is a specification.

The present invention relates to devices which are charged with compressed or liquefied air or gas, and used for inflating lifepreserving belts, pneumatic tires and, in general, in all cases where it is desired to aver air or gas for any desired purpose.

in devices of the kind hitherto proposed, the device herein described utilizes the expansive force of the liquefied gas possessing, at the ordinary temperature, a sufficiently low tension. to enable its beingpreserved in a liquid state in suitable container.

The herein described cartridge difi'crentiates itself more particularly from hitherto proposed devices in that it is not necessary, when it is desired to make use of it, either in unscrew a plug, or slacken a screw, or to operate a lever orother like member in order to bring about the escape of gas. In other words, the cartridge not provided with any special opening or closing contrivance.

Broadly speaking, the invention consists, primarily, in forming a glass container, in such a manner that the closing thereof is obtained by sealing the glass itself, while the opening is obtained by merely breaking, by means of the hand, a determined portion of the container. The said breakage can be performed with the greatest simplicity and, when once effected, it immediately gives rise to the escape of the gas therein contained.

Furthermore, the invention consists in a special sheath or case for the reception of the cartridge.

The accompanying drawing illustrates,by

way of an instance, a cartridge constructed in accordance with the present invention.

Figure 1 is a longitudinal section of the invention and Figs. 2 and 3 are views of life-preserving belts to be used in connection therewith.

Serial No. 125,758.

It is introduced in a sheath 0 of metal or other suitable material, hermetically closed at the bottom by a plug d and provided, at the top, with a nozzle 6 to which is connected, by a ligature or other suitable air-tight means, a-t-ube of somewhat thick rubber 7, actingto protect the neck Z) against accidental fracture. Linings g of rubber or other suitable substance protect the matrass against shocks.

The matrass, which contains air or a suitable liquefied gas, such for instance as sulfurous anhydrid, is sealed at its end by means of a lamp or blow pipe. The neck 7) can be easily broken by the hand.

Into the end of the rubber tube 7" is placed a nozzle h held in place by a ligature or other equivalent means. The said nozzle, which may be of any appropriate kind, is

formed with a screw-threaded hole. 2' by which it can be connected either to a nozzle j on the-life-preseiwing belt is, shown in Fig. 2, or to a pneumatic tire, or to any other contrivance to be inflated or to be supplied with the air or gas stored up in the matrass.

The diameter of the hole 71 is preferably smaller than that in the neck 6, so that when broken, the latter cannot be carried out of the tube f along with the gaseous current. For greater safety, the nozzle h may be lined or provided with a perforated disk or wire cloth Z. Finally, the neck Z) is protected against breakages when the device is not to be used, by a suitable cap a which can be readily removed.

The operation is as follows. The cartridge is connected by means of the nozzle h to a life-belt 7:: for instance, by using the nozzle j into which is fitted, as usual, a check-valve which will let the gas pass during the inflating operation, but will prevent any escape of the gas when once the inflating operation is completed. The operation is the same as in the case of a pneumatic tire.

The operation may, however, be performed in a different manner in the case of life-belts in that, instead of causing the cartridge to act from the outside, as hereinbefore described and as heretofore proposed, it may be caused to act from the interior by placing it inside the belt Is this belt being illustrated in Fig. 3. For that purpose, it

would be sufficient to bore a hole in the wall of the belt, to then introduce the charged neck 6, as already described.

Independently of the above mentioned purposes for which this special arrangement of cartridge is more particularly intended, it is'to be understood that, among other uses, it may also be employed for inflating footballs, india rubber animals or "toys and, in general, for all other applicacartridge.

I claim: 1. The combination of a sealed glass cartridg having a frangible portion With an air-tight casing completely inclosing the same and yieldable to permit fracture of the 2. The combination of a sealed glass car- "tridge having a frangible portion and an air-tight casing completely inclosing the same and yieldable to permit fracture of the cartridge, said casing having means adapted to be eoupledto a device to be inflated.

3. The combination of a sealed cartridge having an elongated relatively small frangible neck, and an air-tight casing completely inclosing the said cartridge and yieldable to permit the neck to be fractured.

4. The combination of asealed glass cartridge having a frangible portion and an air-tight bendable casing completely inclosing the same and having a strainer and a screw-threaded head to be coupled to a de vice to be inflated.

5. The combination of a sealed glass cartridge having a frangible portion and an air-tight casing completely inclosing the same, the neck of said casing being composed of semi-rigid material, and a screwthreaded head adapted to be coupled to a device to be inflated.

6. The combination of sealed glass cartridge and an air-tight casing completely covering the same, the body of the said glass cartridge being securely held in place in the said casing by suitable spacers, the neck of said cartridge being frangible and having a yield able casing, and the head of said casing constructed to be coupled to a device to be inflated.

7. The combination with a sealed glass cartridge comprising a body and an. elongated frangible neck, of an air-tight casing completely covering the body of said cartridge, spacers between said body and casing, the frangible neck of said cartridge having a casing composed of semi-rigid material Which is adapted to permit of fracturing the neck of said cartridge, and means for attaching said casing neck to a device to be inflated.

- 8. The combination of a sealed glass cartridge and an air-tight casing, the neck of said casing being bendable, and provided with a cover to protect against accidental bending of the same, and the head of said casing constructed to be coupled to a device to be inflated.

In Witness whereof, I have hereunto set my hand this 25 day of Sept, one thousand nine hundred and sixteen, in presence of two subscribing Witnesses.
